Technical Field

[0001] This utility model relates to the field of stationery technology, specifically to a notebook with a corner clamping structure. Background Technology

[0002] Notebooks are common study and office supplies used in our lives, consisting of a cover and inner pages, with the inner pages primarily made of writing paper.

[0003] Because paper has a certain degree of water absorption, during use, the user's hands will repeatedly rub against the edges of the paper. The paper fibers absorb the sweat on the user's hands and swell, causing the paper to curl. This greatly reduces the notebook's appearance and integrity, affecting the user experience.

[0004] Therefore, there is an urgent need to provide a notebook with a corner clamping structure. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a notebook with a corner clamping structure.

[0006] The technical solution adopted by this utility model is as follows: A notebook with a corner clamping structure includes a cover panel, a back panel, and a plurality of writing papers disposed between the cover panel and the back panel.

[0007] It also includes a magnetic sheet component, which includes a first magnetic sheet, a second magnetic sheet, and a first connecting member connecting the two. The first magnetic sheet rotates relative to the second magnetic sheet and its adjacent side to have a first attracted state that attracts and clamps the corner of the writing paper located between the two magnetic sheets, and a first disengaged state that moves away from the second magnetic sheet and does not attract it.

[0008] The back panel has a placement slot on its side / bottom that matches the size of the magnetic sheet.

[0009] Preferably, the first connector is a flexible component.

[0010] Preferably, the first magnetic sheet and the second magnetic sheet are both right-angled triangles and are sized to fit each other, and the first magnetic sheet rotates relative to the second magnetic sheet and its adjacent right-angled side.

[0011] Preferably, the magnetic sheet is fixed with a second connector on the side near the placement slot, which is connected to the back panel or the placement slot.

[0012] Preferably, the second connector is a flexible component.

[0013] Preferably, the magnetic sheet is fixed with a second connector connected to the back panel on the side near the placement slot. One end of the second connector is fixed to the right-angled side of the second magnetic sheet that is different from the side connected to the first connector. When the first magnetic sheet and the second magnetic sheet are attracted together, the magnetic sheet can rotate around the connection between the second connector and the back panel to have a first placement position in the placement slot and a second placement position on the writing paper.

[0014] Preferably, the first magnetic sheet has a first contact surface corresponding to the second magnetic sheet and / or the second magnetic sheet has a second contact surface corresponding to the first magnetic sheet, which is provided with a plurality of first raised stripes.

[0015] Preferably, the cross-section of the first convex stripe is semi-circular.

[0016] Preferably, the upper and / or lower end surfaces of the placement groove are provided with a second convex stripe that protrudes towards the center.

[0017] Preferably, a flexible abutment layer is provided on the side of the second convex stripe near the center of the placement groove, and the flexible abutment layer undergoes elastic deformation in the thickness direction when the magnetic sheet is inserted into the placement groove.

[0018] The beneficial effects of this utility model are as follows: When the notebook is not in use, the user can stack the magnetic pieces and place them in the placement slot. Before writing, the user can take the magnetic pieces out of the placement slot and unfold them to clamp the corners of the current writing page or the current writing page and several subsequent writing papers, thereby ensuring that the corners will not curl due to friction during the writing process, and at the same time, it can help restore the corners that are accidentally folded.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0037] Example 1

[0038] like Figures 1 to 6 As shown in the embodiment of this utility model, a notebook with a corner clamping structure includes a cover panel 1, a back panel 2, and a plurality of writing papers 3 disposed between the cover panel 1 and the back panel 2. It also includes a magnetic sheet 4, which includes a first magnetic sheet 41, a second magnetic sheet 42, and a first connecting member 43 connecting the two. The first magnetic sheet 41 rotates relative to the second magnetic sheet 42 and its adjacent side, having a first attracted state that attracts and clamps the corner of the writing paper 3 located between the two magnetic sheets 42, and a first disengaged state that moves away from the second magnetic sheet 42 and does not attract it.

[0039] The back panel 2 has a placement slot 21 on its side / bottom that matches the size of the magnetic sheet 4.

[0040] With this design, when the notebook is not in use, the user can fold the magnetic pieces and place them in the slot. Before writing, the magnetic pieces are removed from the slot and unfolded to hold the corners of the current page or the current page and several subsequent pages, thus ensuring that the corners do not curl due to friction during writing and helping to restore accidentally folded corners. In this embodiment, the slot 21 is located at the bottom of the back panel 2.

[0041] The first connector 43 is a flexible component.

[0042] The flexible connection between the two magnets allows for rotation while maintaining structural simplicity.

[0043] The first connector can be an elastic connecting strip with both ends fixed to one side of the first magnetic sheet and the second magnetic sheet, or it can be a non-magnetic flexible coating that covers the first magnetic sheet and the second magnetic sheet and forms a separating strip between them. In this embodiment, it is specifically in the form of an elastic connecting strip.

[0044] The first magnetic sheet 41 and the second magnetic sheet 42 are both right-angled triangles and are sized to fit each other. The first magnetic sheet 41 rotates relative to the second magnetic sheet 42 and its adjacent right-angled side.

[0045] This design allows the right-angled triangular structure to fit the shape of the writing paper's edges while occupying a small area.

[0046] Example 2

[0047] like Figure 7 As shown, this is a notebook with a corner pressing structure in an embodiment of the present invention. The difference between this embodiment and embodiment 1 is that the placement groove 21 is set on the side of the back panel 2.

[0048] Example 3

[0049] like Figure 8-10 As shown, this is a notebook with a corner pressing structure in an embodiment of the present invention. The difference between this embodiment and embodiment 1 is that the magnetic sheet 4 is fixed with a second connector 44 connected to the back panel 2 on the side near the placement groove 21. The second connector 44 is a flexible part.

[0050] The magnetic sheet 4 is fixed with a second connector 44 connected to the back panel 2 on the side near the placement groove 21. One end of the second connector 44 is fixed to the right-angle side of the second magnetic sheet 42 that is different from the right-angle side connected to the first connector 43. When the first magnetic sheet 41 and the second magnetic sheet 42 are attracted together, the magnetic sheet 4 rotates around the connection between the second connector 44 and the back panel 2 to have a first placement position in the placement groove 21 and a second placement position on the writing paper 3.

[0051] This design prevents the magnetic sheet from being easily lost and also facilitates its removal from the placement slot. The second connector 44 is specifically a flexible connecting strip, fixed to the right-angled side of the second magnetic sheet 42 that is different from its connection to the first connector 43. This prevents interference with the opening and closing of the magnetic sheet 4. Furthermore, after the first and second magnetic sheets are attracted together, they can be rotated around the connecting edge of the second magnetic sheet 42 and the second connector 44 to be inserted into the placement slot 21, further improving the structural simplicity. The second connector is designed to facilitate the removal and insertion of the magnetic sheet into the placement slot.

[0052] Example 4

[0053] like Figure 11-13 As shown, this is an embodiment of the present invention, a notebook with a corner clamping structure. The difference between this embodiment and Embodiment 1 is that a plurality of first convex stripes 45 are provided on the first contact surface 411 of the first magnetic sheet 41 corresponding to the second magnetic sheet 42 and / or the second contact surface 421 of the second magnetic sheet 42 corresponding to the first magnetic sheet 41. The cross-section of the first convex stripe 45 is semi-circular.

[0054] This setting increases the friction between the writing paper and the magnetic surface.

[0055] The upper and / or lower end faces of the placement groove 21 are provided with a second convex stripe 211 that protrudes towards the center. The cross-section of the second convex stripe 211 is specifically semi-circular. Through this setting, stress is concentrated, improving the stability of the magnetic sheet in the placement groove, making it less likely to fall out, and at the same time, making it easier to remove and insert the magnetic sheet.

[0056] A flexible abutment layer 212 is provided on the side of the second convex stripe 211 near the center of the placement groove 21. This flexible abutment layer 212 undergoes elastic deformation in the thickness direction when the magnetic sheet 4 is inserted into the placement groove 21. This design further improves the ease of removing and inserting the magnetic sheet, reduces the risk of damage, and, when the magnetic sheet is in the placement groove, the elastic deformation of the flexible abutment layer in the thickness direction provides a certain reaction force to the magnetic sheet, further improving the stability of the fit between the magnetic sheet and the placement groove. The flexible abutment layer can be made of materials such as rubber.

[0057] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
